Can a solvent-engineering approach be applied to other perovskite solar cells?

Can anti-solvent crystallization be used to fabricate Tin/Tin perovskite solar cells?

What solvent is used to make a perovskite film?
This initiates nucleation and crystallization, which in turn passivates defects and results in the production of a uniform and compact perovskite film. However, the early developed ASAC methods typically employed traditional toxic solvents such as chlorobenzene (CB), 18–20 toluene (TL), 21,22 and ethyl ether (DE) 23,24 (outlined in Table 1).
Can anti-solvents improve perovskite thin film quality?
Our study reveals that the utilization of anti-solvents advances substantial strengths, such as enriched crystallinity and improved optical properties, leading to a flexible method for tailoring perovskite thin film qualities.
